This is the second installment of our series on data center equipment and maintenance. Among the types of equipment that require mechanical maintenance in a data center are HVAC chillers.
HVAC chillers are widely used in data centers to cool the water used for heating, ventilation, and AC units. Since these chillers often run nonstop, it is essential that they are well-maintained for optimal functioning. Without HVAC chillers, temperatures in data centers would quickly rise, causing malfunctioning of hardware and loss of important data. In addition, HVAC chillers make close-proximity servers possible.
It is also important to note that independent generators are essential for chillers in the event of a power grid fail.
Let’s break down some important numbers:
Additionally, according to a report released in 2016, it is estimated that U.S. data centers account for two percent of the country’s total electricity usage, and they continue to grow! This means that the need for efficiency and decreased downtime is essential. It is also estimated that data centers consume as much energy as 6.4 million average American households.
Several methods of cooling servers are:
Using simulation software such as SimScale to test out computational fluid dynamics (CFD) can be helpful in determining which method or combination of methods of cooling is best for your data center.
Some strategies for more efficient cooling of servers include:
Here are some additional tips for maintaining optimal functioning of data centers and ensuring servers are kept cool:
